SOURCE: Car petrol engine revolution surges.

Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: Hi we have a Mazda

if you look under the hood there is a fuse box that will have a large fuse that is labeled btn. what you need to do is pull this fuse and then hold the brake pedal for about a minute. we call this fuse the back to normal fuse because when you do this it will clear every thing in the memory and put it back to normal operating specs

My daf xf 480 an error in speed engine, it maximum 2000 rpm, what i have to do?


take it to a DAF service center or have a technician come out to inspect the fault
with limited engine rpms it is possibly in limp mode where the ECM restricts the engine speed and vehicle speed because it has registered a fault that is detrimental to the engine or transmission
LImp mode is only available to allow the vehicle to get to a safe place to stop so that the codes can be read and repairs effected

Driving engine does not rev over 2,000 rpm 2002 crv is auto in question


by limiting the rpms to 2000 it is an indication that the ECM is in limp mode to protect either the engine or transmission. I suggest a fault code reading before you go any further as guesses just cost money.

Engine hunting under accelaration


It sounds like your 9-3 is in Limp-Home mode. In which case, you are right - it is hitting a temporary limiter. The most typical of the causes I see are from an aging Direct Ignition Cassette (DIC). When there is a fault detected in the DIC module, the throttle body lets the throttle spring kick down to what is known as Limp-Home mode. Although it can be ratcheted back to the normal position, if the DIC misfire is detected again, the same will happen. I'd have a shop take an OBD-II reare to it and confirm. If it is the DIC, replace it, and have them reset the error code and the throttle body.

I hope this get you back on the road quickly with your Saab! (I drive one, too)

Reduced engine power


Your vehicle seem to have gone into limp home mode. You need to have the fault codes pulled to know what is wrong. Limp mode lets you get home but limits engine output function.

Navara d40 has no power wont rev more than 3000 rev thanks


Sounds like your vehicle is in limp mode. Check for faults with a fault code scanner at a local auto parts store. Resetting the fault will fix the limp mode, but not whatever caused your vehicle to initiate limp mode.

Vauxhall combo duel fuel/engine management light comes on and i lose power


The engine has gone into limp mode because of a fault. When this happens the engine managment system shuts down some of the power to prevent damage to the engine and its components. Best bet is to take it to a garage and have them run a diagnostic check to see if any fault codes are showing.

Igot a vauxhall astra 1.8 sri igot a light cum on the dash its a car with a spanner threw it when on the engine idles bad


This is your mechanical fault light and the lack of power is the car going into limp mode to protect the engine and its components.
Have a garage run a diagnostic check to find the fault code and the fault.
Hope this helps
